Novel Ceramic Coatings for High Temperature Applications

陶瓷涂层用于保护航空发动机和发电行业等高温应用的底层基材。几种传统的涂层技术已被用于施加陶瓷涂层，但需要更可靠的涂层来提高这些涂层的性能和寿命。该项目旨在开发一种新的涂层技术，以生产具有可控微观结构的涂层。更重要的是，这些涂层的性能和性能将在这些涂层的微观结构进行检查。本项目的目标是：1）开发一种新的涂层技术; 2）检查使用这种新的涂层技术生产的涂层的微观结构和性能; 3）了解涂层在腐蚀环境下的性能。在该项目中，各种陶瓷加工技术将用于生产陶瓷涂层。此外，一系列材料表征技术将用于检查涂层的微观结构，残余应力和机械性能。将研究涂层在腐蚀环境下的降解机理。目的是开发比使用当前涂层技术生产的涂层更可靠的新涂层。该项目属于EPSERC材料工程研究领域-陶瓷和能源应用材料。

Ceramic coatings are being used to protect the underline substrates for high temperature applications like aero-engine and power generation industry. Several traditional coating techniques have been used to apply ceramic coatings but more reliable coatings are required to enhance performance and lifetime of these coatings. The project intend to develop a novel coating technique to produce coatings with controlled microstructure. More importantly properties and performance of these coatings will be examined in relation to microstructure of these coatings. The objectives of this project is 1) develop a novel coating technique; 2) examiner the microstructure and properties of the coatings produced with use of this novel coating technique; 3) understand performance of the coatings under corrosive environments. During this project various ceramic processing techniques will be used to produce ceramic coatings. In addition, a range of materials characterization techniques will be used to examine microstructure, residual stresses and mechanical properties of the coatings. The degradation mechanisms of the coatings under corrosive environments will be examined. The aim is to develop new coatings which are more reliable than the coatings produced with use of the current coating techniques. The project is within the EPSERC research area of Materials Engineering- ceramics, and materials for energy applications.
